The third connection portion 811 is formed by bending a part of the base end side of the vertical third shaft portion 821 substantially at a right angle. The third connection portion 811 is provided with an insertion hole for inserting the suspension bolt 201, and the insertion hole is formed in a U shape with a part thereof opened (not shown). ). On the other hand, the third connecting portion 811 is provided with a folded portion 811b at the end. The folded portion 811b is formed by folding the end portion of the third connection portion 811 vertically downward so that the third shaft portion 821 is substantially parallel. Further, the third connection portion 811 is provided with a second folded portion 811c at an end portion adjacent to the end portion where the folded portion 811b is provided. These folded

portions

811b and 811c restrict the movement of the suspension member 801 in the horizontal direction. Therefore, according to the suspension device 80, the suspension member 801 having the two folded

portions

811b and 811c can prevent the suspension member 801 from falling off the suspension bolt 201.

Third support portions

831a and 831b formed horizontally by bending a part of the base end side of the third shaft portion 821 substantially at a right angle are provided on the base end side of the third shaft portion 821. However, the

third support portions

831a and 831b are constituted by two support portions that are formed by being divided substantially in the vicinity of the center in the width direction and bent in opposite directions. One third support portion 831a is inserted from the opening 14 into the groove portion 15 of the beam 1 and contacts the lid portion 16 on one side (the left side in FIG. 15) to support the beam 1. The other third support portion 831b is inserted from the opening portion 14 into the groove portion 15 of the beam 1 described above, and contacts the lid portion 16 on the other side (the right side in FIG. 15) to support the beam 1. When the beam 1 is suspended using the suspension device 80, the suspension device 80 may be inserted in advance from the end of the beam 1 and the suspension device 80 may be fixed to a predetermined suspension bolt 201. The suspension device 80 is merely an example, and existing technology can be appropriately used for the suspension device. For example, the suspension device may be constituted by two suspension members that can be separated. In this case, each support part can be inserted into the groove part 15 from above the groove part 15.

<How to use>
The connection between the beam 1 and the beam coupling member 2 is performed using screws. Specifically, the screw is screwed halfway into the central portion 11 formed of a screw hole at the center of the end of the beam 1. The head of the screw protruding from the end of the beam 1 is passed through the first region 216a of the through hole 216 and slid downward. When the screw is tightened to the end with the shaft portion of the screw positioned in the second region 216b, the beam 1 and the beam coupling member 2 are fixed. At this time, the elongated protrusion 217 of the beam coupling member 2 is fitted into the groove of the beam 1. The movement of the beam 1 is regulated by screwing with the screw, but the movement of the beam 1 is further regulated by fitting the elongated protrusion 217 of the coupling member 2 of the beam with the groove of the beam 1. When the beam 1 is suspended using the above-described suspension device 80, the suspension device 80 may be inserted in advance from the end of the beam 1 and the suspension device 80 may be fixed to a predetermined suspension bolt 201.

The connection between the beam coupling member 2 and the support member A6 is also performed using screws. Specifically, the base 61 of the support member A is placed on the upper portion 21 of the beam coupling member 2. Insert the screw from the base A61 side with the claw portion 214 and the notch 611 of the beam coupling member 2 engaged, and the upper screw hole 212 of the beam coupling member 2 and the screw hole 613 of the base A communicating with each other. And screw together. Thereby, the supporting member A6 is fixed to the coupling member 2 of the beam.

The connection between the support member A6 and the horizontal brace 4 is also performed using screws. Specifically, the first surface of the connecting member 7 of the horizontal brace connected to both ends of one horizontal brace 4 of the pair of intersecting horizontal braces 4 is on the upper side (as shown in FIG. The connecting member 7 of the horizontal brace is fixed to the supporting member A6 of the horizontal brace with screws. In addition, the connecting member 7 of the horizontal brace with the first surface of the connecting member 7 of the horizontal brace connected to both ends of the other horizontal brace 4 facing down (unlike FIG. 3, the stepped portion 73 faces upward). Is fixed to the support member A6 of the horizontal brace. Thereby, the connection height of the horizontal braces 4 connected so that the stepped portion 73 faces downward becomes higher than the connection height of the horizontal braces 4 connected so that the stepped portion 73 faces upward. As a result, contact between horizontal braces can be suppressed. The horizontal brace 4 can adjust the tension of the horizontal brace 4 by relatively rotating the horizontal brace 4 and the horizontal brace adjusting member 31 or the horizontal brace connecting member 7.

<< Effect >>
According to the structure 3 according to the first embodiment, the strength of the structure 3 can be improved by providing the horizontal brace 4. Further, since the horizontal brace 4 is located above the beam 1 and the horizontal brace 4 is located outside the constructed space, the installation location of the equipment (lighting, projector, etc.) is not limited. Accordingly, the degree of freedom in designing the space to be constructed can be further increased. Moreover, since the horizontal brace 4 is located outside the space to be constructed, the aesthetics of the space to be constructed is not impaired, and the design is improved.

Further, in the beam coupling member 2 according to the first embodiment, the screw fixed to the end of the beam 1 is inserted into the through-hole 216 of the beam coupling member 2 and the screw is easily tightened. The connecting member 2 of the beam can be connected. As a result, the beams 1 can be easily combined. Further, the beam coupling member 2 is provided with the elongated protrusions 217 that fit into the groove portions 15 of the beam 1 on both sides of the through-hole 216, so that the movement of the beam 1 can be restricted. As a result, the strength of the structure 3 constructed by combining the beams 1 can be further improved. The through-hole 216 includes a first region 216a through which a head having an outer shape larger than the shaft portion of the screw can pass, and a second region 216b which continues below the first region 216a and allows only the shaft portion of the screw to pass therethrough. Is provided. Therefore, unless the beam 1 is moved upward against gravity, the screw does not come out of the through hole 216. Therefore, the fixed state can be more reliably maintained as compared with the case where the positional relationship between the first region 216a and the second region 216b is reversed.

Also, a horizontal brace support member B40 is connected to the beam 1 at the T-shaped portion, and the horizontal brace 4 is supported by the support member B40. The description of the same configuration as in the first embodiment is omitted by attaching the same reference numerals.

The T-shaped part is formed by connecting the end of the beam 1 to the side surface of the beam 1. Since the existing technique can be used as appropriate for the connection between the side surface of the beam 1 and the end of the beam 1, the description thereof is omitted. Examples of the existing technology include a connecting means described in Patent Document 1 (International Publication No. 07/055039 pamphlet).

The support member B40 includes a base part B41, a shaft part B62, and a brace receiving part B63. The base B41 has a rectangular plate shape and is slidable in the groove 15 of the beam 1. The base B41 is provided with a screw hole 411 of the base B, and is aligned with the screw hole 702 of the slide coupling device 700 slidable in the groove 15 and screwed into the support member B40. It can be fixed to the beam 1.

<< Slide coupling device >>
Here, FIG. 24 shows a perspective view of the slide coupling device according to the second embodiment. The slide coupling device 700 includes a base member 701 and an auxiliary member 710. The base member 701 is quadrangular in plan view, and a screw hole 702 is provided at the center. A step formed at the end of the surface of the base member 701 (the surface of the groove 15 on the opening 14 side) (both ends in the width direction of the groove 15) one step lower than the surface along the longitudinal direction of the groove 15. Attached portion 703 is provided. The distance between the two stepped portions 703 is designed to be slightly smaller than the width of the opening 14 of the beam 1. Each stepped portion 703 engages with a lid portion 16 that forms the opening 14. Thereby, the base member 701 is restricted from moving in the groove 15 in the width direction of the groove 15. Further, the end portions (both ends in the width direction of the groove portion 15) of the back surface (the back surface of the groove portion 15) of the base member 701 are chamfered 704 so as to match the shape of the groove whose width becomes narrower toward the back. ing.

The auxiliary member 710 includes a main body portion 711 on which the base member 701 is placed in the groove portion 15 and two arm portions 712 extending from the end portion of the main body portion 711. The auxiliary member 710 is made of a flexible plate-like resin, and the main body portion 711 and the arm portion 712 are integrally formed. The main body 711 is curved so as to protrude to the back side of the groove 15. The main body 711 is designed to have an area larger than the surface area of the base member 701 so that the base member 701 can be placed thereon. A screw hole 713 of the main body through which the screw 750 passes is provided at the center of the main body 711, in other words, at a position corresponding to the screw hole 702 of the base member 701. A plurality of screw holes 713 may be provided. Further, a thick portion formed thicker on the side of the opening 14 than the periphery is provided on one side of the main body 711. The thick portion regulates movement of the mounted base member 701 in the width direction of the groove, and functions as a region for pressing the auxiliary member 710 when the auxiliary member 710 is attached (accommodated) to the groove portion 24. The auxiliary member 710 can be easily attached to the groove portion 24 by pressing the thick portion. The thick portion also functions as a fulcrum when the arm portion 712 is picked and the auxiliary member 710 is taken out from the groove portion 15. That is, the thick portion is in contact with the inner wall surface of the groove portion 15 and becomes a fulcrum, and when the arm portion 712 is picked and pulled out from the groove portion 15, the main body portion 711 of the auxiliary member 710 is taken out from the groove portion 15.

In addition, the main body portion 711 has a thick portion and a bent portion of the other piece in contact with the inner wall of the groove portion 15 and urges the inner wall of the groove portion 15 toward the outside of the width of the groove portion 15. Thereby, the auxiliary member 710 is temporarily fixed in the groove 15. More specifically, in a state where the main body portion 711 does not place the base member 701 (a state where only the auxiliary member 710 is accommodated in the groove portion 15), the thick portion and the bent portion are included in the inner wall of the groove portion 15, The inner wall of the groove 15 is urged toward the region (vertical surface) where the width of the groove 15 is constant toward the outside of the width of the groove 15. Further, in a state where the main body portion 711 places the base member 701 (a state where both the auxiliary member 710 and the base member 701 are accommodated in the groove portion 15), the thick portion and the bent portion are included in the inner wall of the groove portion 15. The inner wall of the groove 15 is urged toward the region (slope) in which the width of the groove 15 gradually narrows toward the outside of the width of the groove 15. Note that in a state where the main body portion 711 places the base member 701, a part of the urging force is also generated on the back side of the groove portion 15 along the slope.

Further, the main body 711 is formed such that the length on one side is shorter than that on the other side. Specifically, in the main body 711, the length on one side of the virtual center line parallel to the longitudinal direction of the groove 15 passing through the center in the width direction of the groove 15 is longer than the length on the other side of the virtual center line. , The two arm portions 712 are formed shorter. In other words, one side of the main body 711 is notched on both sides in the longitudinal direction of the groove 15. Thus, the urging | biasing force is adjusted by forming a notch in part.

The arm portion 712 is provided at two places via bent portions provided at both end portions on the other side opposite to the thick portion. The arm portion 712 is curved so as to protrude to the back side of the groove portion 15. In addition, a thick part of the arm that swells toward the main body 711 is provided at the tip of the arm 712. The thick part of the arm is exposed from the opening 14. Thereby, the slide coupling device 700 can be easily taken out from the groove portion 15 by gripping the thick portion of the arm portion. Further, the base member 701 placed on the main body 711 is sandwiched between the two arm portions 712 on both sides in the longitudinal direction of the groove 15, and the movement of the groove 15 in the longitudinal direction is restricted. Further, the movement of the groove portion 15 in the width direction is restricted by the engagement of each stepped portion 703 and the lid portion 16 forming the opening portion 14. Further, the movement of the groove 15 in the back direction is restricted by the base member 701 and the opening 14.

A space is formed between the main body portion 711 and the arm portion 712 in the vicinity of the bent portion 714. By forming this space, the arm portion 712 can be sufficiently bent toward the main body portion 711 side. As a result, the auxiliary member 710 can be easily taken out from the groove 15. The biasing force can be changed by appropriately adjusting the material and thickness of the auxiliary member 710, the area of the main body portion 711, the diameter of the screw hole 702 of the main body portion, the thickness and width of the arm portion 712, and the like.

When attaching or removing the slide coupling device 700 to or from the groove 15, it can be attached or removed from the end of the beam 1. Further, the slide connecting device 700 may be attached and detached from the opening 14 of the groove 15 of the beam 1.

<< Effect >>

A wall surface 93 extends from one vertex P toward the adjacent vertex P. A wall surface 93 extending from one apex P and a wall surface 93 extending from another apex P adjacent to the apex P extend to the middle before both apexes P, and they do not contact each other. Accordingly, an opening 94 is formed between the opposing wall surfaces 93 and 93. Further, a groove portion 95 is formed by the pair of wall surfaces 93, the partition wall 92, and the central portion 91. The opening 94 and the groove 95 extend over the entire length in the axial direction of the pole 9. The opening 94 is formed narrower than the space in the groove 95. The lid portion 96, which is the tip portion of the wall surface 93, suppresses the insertion of the insert into the groove portion 95 and functions as a contact portion when supported.

The pole 9 has an outer wall surface 97 corresponding to the outer wall surface 17 of the beam 1 in four directions. A wiring groove 98 that is a semi-closed space is formed on the surface of the pole 9 by the opposing outer wall surface 97 and the pair of wall surfaces 93 connected to these. In this wiring groove 98, for example, a cable of a lighting fixture or a cable of an information device can be stored. In addition, you may provide a cover in the groove part for wiring, and this can improve design property.
